Better Handling of Copilot Limits

[minibikini]

I'm a GitHub Copilot free user and recently started using it with Zed Editor. The combination works wonderfully, but I've encountered an issue where code completions suddenly stopped working. Initially, I suspected that I might have hit the free-tier limits, but there was no notification in the Zed Editor UI. It just stopped working without any warning.

Upon checking Zed's log, I found a message from the Copilot Language Server indicating that I had reached my monthly code completion limit. Now I understand what happened, but it would be incredibly helpful if Zed could provide a clear notification when a user has reached their API usage limits.

Here is the log message I found:

2025-02-04T04:06:40.529896+04:00 [INFO] Language server with id 0 sent unhandled notification window/showMessageRequest:
{
  "type": 2,
  "message": "You've reached your monthly code completion limit. Upgrade your plan to Copilot Pro (30-day Free Trial) or wait until 2025-03-31 for your limit to reset to continue coding with GitHub Copilot. You are currently logged in as minibikini.",
  "actions": [
    {
      "title": "Upgrade your plan"
    },
    {
      "title": "Dismiss"
    }
  ]
}

Not sure if it's a bug report or a feature request so opening a discussion.

This also stopped working for me, I'm getting the following along with the error @minibikini reported.

Thanks for reporting. As a workaround, if you are using Copilot Free tier you can conserve you completions by switching to manually triggered completions. Do this by unchecking "all files" in the copilot menu.

Then you can trigger editor::ShowEditPrediction manually (alt-tab on macos, alt-\ on linux) and make your 2000 monthly completions go a lot further.
